The worst case analysis of rounding error of eleven numerical
quadrature formulas on a computer with floating-point arithmetic,
base b, and t digit mantissa is calculated. These results are
applied to five different integrands using the digital computer CDC
3300 located at Oregon State University. Central processing unit
computing time,...
It is popular belief that the volatility of the exchange rate is due
to the balance of payments, which in turn is mainly influenced by the
balance of trade. A closed-loop dynamic economic model is proposed
to describe and analyse the effect of the international trade of a
country on...
A series of four trials was conducted to evaluate activated
sewage sludge (AcSS) as a protein source. In the first trial the protein
efficiency ratio (PER) of sun-dried and auto-claved, sun-dried
AcSS was measured with rats. Growth of AcSS-fed rats was extremely
poor as compared to those rats fed casein,...
Numerical simulation of the January and July global
climate with the OSU two-level atmospheric general circulation
model has generated time series of the global
distribution of selected climatic variables. Analyses of
these data for the kinetic energy and available potential
energy based on 31-day time mean statistics have been
made...
A variational integral method in the Fourier transform domain is
used to calculate the characteristic normal mode parameters of a coupled
pair of nonsymmetrical microstrip transmission lines in an inhomogenous
dielectric medium under quasi-TEM conditions. These together with the
theory of such structures are used to show that ideal directional...
The low temperature geothermal resource at Klamath Falls,
Oregon is widely used for heating buildings. A common technique
for using this resource consists of a heat exchanger down in the
well inside a casing which extends the full length of the well.
Slots are cut in the casing to allow...
Diagnoses, synonymies, range maps, and an illustrated key are provided
for the six species of Agapostemcn found in the Northwest: A. angelicus, A.
coloradinus, A. femoratus, A. melliventris, A. texanus, and A. virescens.
Adults of both sexes of A. virescens share a nest. Peculiar linearly paired
male-female cells in nests...
Members of the deltocephaline leafhopper genus Giprus Oman
live on grasses, primarily in the desert-scrub, chaparral, and
marine sand dune communities of western North America. Of 16
known species, 10 are undescribed. Recharacterization of the genus
results in exclusion of Laevicephalus incongruus Oman. Differentiation
of species is primarily dependent on...
